Pier, Smalltalk and XSLT

I'm currently investigating approaches to an update/rewrite of a publishing system we've developed (using Rails) which takes publications stored as Docbook XML and renders a series of webpages with navigation according to a set of common themes switched by metadata in the source file. Pier looks a promising candidate, either on Squeak or Gemstone/S, but I get the impression that Smalltalk XSLT libraries are fairly scant. Is this right? I guess there would be the approach of calling out via a web service or FFI to other libraries, but any advice would be appreciated. -- International Baccalaureate Steve Lloyd Research Engineer Publications group Peterson House, Malthouse Avenue, Cardiff Gate, CARDIFF CF23 8GL, United Kingdom Tel: +44 29 2054 7869 Fax: +44 29 2054 7778 Web: http://www.ibo.org
